AUXILIARY APPARATUS FOR CONDENSERS.

Application filed April 26, 1922. Serial No. 556,719.

To all whom it may concern:

Be it known that 1, ROBERT SUozEK, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Auxiliary Apparatus for Condensers, of which the following is a specification.

My invention relates to apparatus for removing liquid or gas, or both, by ejector action, from a region or regions of lower pressure to aregion orregions of higher pressure; and more particularly, my'mvention relates to apparatus for removing conden'sate or air, or both, from a condenser.

My invention resides in apparatus for removing condensate from a condenser or liquid from a receptacle comprising an ejector submerged in the condensate or liquid for delivering it to or against higher pressure, the ejector apparatus comprising one or more mixing cones or guide tubes disposed in alignment with and between the motive-fluid-delivering means and the discharge tube or difluse'r.

My invention resides in other features of, and in combination with, ejector condensate or liquid-removing apparatus.

For an illustration of some of the various forms my invention may take, reference is to be had to the accompanying drawing, in which:

The figure is a vertical sectional view, some parts in elevation, through a con denser and associated condensate-removing means.

Referring to Fig. 1, C represents the shell of a condenser, for example, the shell of a surface condenser having the inlet E for the steam to be condensed, such as steam exhausted from a steam turbine, engine, or

from any other suitable source. Air and uncondensable vapors or gases are removed from the condenser C through the port O by any suitable means, for producing or maintaining within the condenser C the .usual high vacuum.

Thesteam entering at E is condensed in well known manner into water, which is the condensatewhich collects in the bottom of the shell C and is delivered to any suitable type of pump P driven by the steam turbine T or any other suitable motor, as an electric motor. When the motor T is a steam turbme, 1t receives steam, as llve or hlghpres sure steam, through the pipe 8 and exhausts it at lower pressure through the pipe or conduit 8 controlled by the valve V. Branched from the exhaust pipe 8 is the pipe U, controlled by valve V and communicating with the pipe 5 controlled by the valve Y and communicating with the nozzle N. Communicating with the pipe 8 is another pipe s controlled by the valve V and connected with any suitable source of motive fluid, as live steam. Upon th upper surface W of the liquid or condensate 001 lecied in the bottom of the condenser C,

and in hot well H is the float F, carried on the end of the lever m secured upon the pivotal shaft 6, which extends through a vacuum-tight joint to the exterior of the condenser shell 0, where there is secured thereto the link X pivotedat n to the link to pivoted at 3 to the link 2, whose other end is secured upon the pivotal shaft v upon which is secured the valve Y.

With the valve V closed and the valves V and V open, the steam turbine T drives the pump P to remove condensate from the receptacle H and discharges the same against atmospheric or any other pressure, as into a boiler against boiler pressure, the exhaust steam from the turbine passing through the pipe 8 and valve V to atmosphere, or to a condenser, feed water heater, or to any other suitable point.- Simultaneously, live or high pressure steam admitted through the valve V and pipe 8? ands passes the open valves Y to the nozzle N, in and by which it is expanded into a jet which draws into the members B, B and 13 the condensate in the receptacle H, delivering the same through the.

diffuser D at higher pressure to the pump P, thus causing the pump P to operate with an effective submergence greater than that due to the height of water level W in the absence of the ejector.

Or with the valves V and V closed and the valve V open, the ejector nozzle N is supplied with low pressure or exhaust steam from the turbine T, in which case the action is again similar to that above described. Or when using exhaust or low pressure steam as described, high pressure or live steam may also be used simultaneously by partially opening the valve V, which throttles the high pressure or live steam to a pressure substantially the same as the exhaust steam delivered through pipe U.

Or exhaust steam from any other source than the turbine T may be employed; for example, the exhaust steam may be derived from the turbine or engine driving the pump which supplies the cooling water to the cool-' ing water system of the condenser C.

The motive fluid, whether high or low pressure steam, or'whether a mixture of them, delivered to the nozzle N, is con-' trolled by the float F. In case the water level \V falls, the float descends, and through the system of levers described moves the valve Y toward closed position, thereby shutting oii more or less completely the supply of motive fluid to the nozzle N, with the result that the submerged ejector removes or assists in removing less condensate, thereby causing the level to again rise to maintain proper submergence of the ejector. In case the water level W falls sutiiciently, the valve Y will be completely closed until the water level-rises to sufficient extent, in which case the float F will again open the valve Y and cause the ejector again to operate and remove condensate.

The motive fluid delivered t'o the sub/'- merged e ector is accordingly controlled 'fi nresponse to changes in rate of discharge of condensate from the hot well H or in response to changes in demand or requirements for the liquid or condensate beyond the diffuser D or pump P.

While steam or other elastic fluid is preferred as the motive fluid, it will be understood that liquid, as water, may be utilized as motive fluid. When the preferred motive fluid, as steam, is employed, and particularly when it is low pressure or exhaust steam of otherwise small value, it is most economically employed. Furthermore,

Gil

whether high or low pressure steam be employed, the heat content thereof is delivered into the condensate, due to condensation of the steam thereby, and the heat gained by the condensate is a factor of economy when condensate is returned to a boiler or through a feed water heater or econom'izer, or both, to a boiler,

The of motive fluid issuing from the means? 1 ing tube B liquid directly from the hot well H, the liquid being then discharged by the diffuser D at higher pressure.

The float F may control the action of the ejector in any other suitable way, as by adjusting an adjustable difluser or adjustable nozzle, or both.
